Abstract
PURPOSE:To enable information to be securely correctly judged when same information is received in a plurality of successive frames to be judged correctly transmitted, by prohibiting any change in transmitted information until the information of a predetermined number of frames is transmitted. CONSTITUTION:On-vehicle information is transmitted periodically from an on- vehicle device 3 through an on-vehicle piece 4 while a vehicle 2 travels on a track 1 in the direction of arrow. When the on-vehicle piece 4 approaches an on-ground piece 5, the on-vehicle information from the on-vehicle device 3 is received by the on-ground piece 5 connected to a processor 7 for decoding the on-vehicle information through a relay 6. Then, the relay 6 is constituted from a relay section 61 and a transmitted information change prohibiting section 62. Said section 62 functions to prohibit any change in the transmitted information until the information of a predetermined number of arms needed to judge whether or not the received information is correct in the on-vehicle device 3 is transmitted.
